Can i downgrade to Lion?

I bought my retina as Lion but upgraded to Mountain Lion. But i think Mountain Lion takes too much battery up, so I should downgrade... is that possible to do myself? Or do i need to go to the store?

As your computer came with Lion, it's easy to reinstall Lion on the MacBook. Follow these steps:
1. Back up your data, so you can restore it after erasing the disk.
2. Press Command, Option and R keys while your Mac is starting to boot into Internet Recovery.
3. Open Disk Utility, select Macintosh HD in the sidebar, go to Erase tab and erase the disk.
4. Close Disk Utility and reinstall OS X. Mac OS X 10.7.5 will be installed on the hard drive

  • How can I downgrade from Lion to Snow Leopard?

    Hello.
    Yesterday, I upgraded my Mac to Mac OS X (10.7 Lion) from 10.6.8 Snow Leopard. However, I wish to downgrade.
    Obviously, I would like to not lose any data at all. However, I have never downgraded before.
    I still have the Snow Leopard installation disk that came with my Mac.
    How should I do this? I was thinking it would be easiest to simply head on over to an Apple Store...
    I did some research (aka Googling), and I read up on the subject quite a bit.
    If I simply put in the disk, will I be able to downgrade from Lion to Snow Leopard as easily as the upgrade was?
    Also, I have heard about holding down the "C" button to do this... how exactly?
    I have never backed up my Mac, nor used Time Machine.
    Also, is it possible to install Snow Leopard on a separate disk, and set it up so that I can switch between them on command?
    Will all of my preferences be saved, or does this wipe everything, not just the system and libraries folders?
    I realize that I have a lot of questions, and therefore I appreciate everyone's help in advance. Thanks again.
    Sincerely, Zach

    Backup your files.
    Booting From An OS X Installer Disc
    1. Insert Snow Leopard Installer Disc into the optical drive.
    2. Restart the computer.
    3. Immediately after the chime press and hold down the "C" key.
    4. Release the key when the spinning gear below the dark gray Apple logo appears.
    5. Wait for installer to finish loading.
    Erase Drive
    1.  Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Upon completion quit DU and return to installer. Install Snow Leopard. Restore your files after the installation has completed.

  • Mountain Lion causing apps not to work, how can I downgrade to Lion without Time Machine Back-up?

    Since installing Mountain Lion, I have found applications that don't work.  I want to go back to Mountain Lion, unfortunately I had trouble with my Time Machine back up hard drive a couple days after installing Mountain Lion and I don't have any back up to work from.  Tried to go to App Store and redownload Lion from there under purchases, but I got message that said "You can’t upgrade this version of Mac OS X because a newer version is installed."
    I have another mac that I can download the Lion install package to and then drag it over to this computer, so the question is, Will I be able to re-install Lion over the upgraded Mountain Lion without any problems?

  • Can I downgrade from Mountain Lion from a Macbook with Mountain Lion as the pre-installed OSx?

    I had to get a new Macbook during my last semester due to my 13" Macbook Pro dying on me. My new 15" Macbook Pro came with Mountain Lion on it and I am not a huge fan of it. I am wanting to revert to Lion if that is possible for my Macbook. I do have a number of back ups of my 13" Macbook with Lion on it, but I tried it before using cmnd /r and it couldn't go back to my Lion back ups. I am not sure if I just did something wrong while I was trying to use my back up or if Macbooks with ML as the pre-installed OSx just can't go backwards.
    Any help would be much appreciated

    you can't revert/ downgrade diffrent OS version.the option only upgrade.
    solutions for this kind problem.
    fresh install lion (use fresh installer version,you can buy or download lion's master)

  • Can i downgrade my macbookpro (model indentify 11.1) to mountain lion, it comes with maveri

    can i downgrade my macbookpro with a last generation of proccessor intel (model indentify 11.1) to mountain lion, it comes with maveric. i want to do this because the software that i work can´t run in maverick

    I'm assuming that since you bought a new MBP that you don't have a copy of Mountain Lion? If not, I don't think you can find it on the app store anymore but you may be able to find a bootable disk elsewhere, ie. the apple support pages. If you have a copy of Mountain lion, then you should be in luck.
    First, if there are any files you want to save, you will want to copy the individual files to another drive so as to save them. You probably don't want to use time machine for this because not everything is backward compatible between the OS's.
    Once you obtain a bootable version of Mountain Lion, do this.
    Insert the recovery disc via USB or optical bay. (I think it may HAVE to be a USB stick, 4gb min)
    Shut down your computer. Wait for it to power down completely.
    Power on your computer while pressing and holding cmd + R.
    Once the page loads, Select Disk Utility.
    Erase the hard drive.
    Shut down computer.
    Reboot computer.
    After that, wait until progress bar is finished and then you should be able to install Mountain Lion.
    Good Luck!

  • I have inastalled Lion on my Mac Book Air and I have really problems. By application that are not from Apple the processors is 80 degrees celsius warm after 2-3 Minutes from the start of the Apps.How can I downgrade 2 Snow Leopard without 2 loose my Data?

    Can I use the Lion licence with my MacBook Pro if I downgraded my Air?

    If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
    If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
    As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.
    If there are specific tasks you need help with:

  • Can I downgrade mail from Lion Mail(v.5) to Snow Leopard Mail(v.4)?

    I just bought a new MacBook (13.3" running Lion OS 10.7.1). I -really- don't like the new format of mail and have problems with searching and other organization methods I worked out. I would like to downgrade from Lion Mail (v.5) to Snow Leopard Mail (v.4). I understand that some people have downgraded the whole operating system and saw those instructions in the discussion forums, but I would like to -only- downgrade mail. Any ideas?
    Also, any recommendations on reducing my load times and delays in mail? I have over 100,000 emails over the past 4 years that are bogging down the system. I have tried archiving some older messages, but the system freezes and then downloads all the attachments from my oldest messages, filling up the entire hard disk. Thanks in advance!

    There is a long thread about this -- https://discussions.apple.com/message/15733107#15733107 -- and the bottom line is that it is possible to install and run SL on a 2011 mini (with some rather wonky hacking...) BUT it doesn't work very well.  Performance benchmarks of the same machine in SL and Lion show the SL as definitely slower.
    Plus people are having problems with certain features on the machine not working.
    I think that your performance issues sound like something else is wrong...  The 2GB is a definite problem -- do you know that you can buy 8GB for the machine for $60, and getting it installed is a snap?  But the first thing that I would do is to install applejack and boot into single-user mode and run disk repair (aka fsck.)  Another question -- if you look on your console, do you see a voracious cpu-eating process called mds?  It's the indexer for Spotlight, and there is nothing to be done about it than to just wait it out, and your machine will work much better when it is done.  And Spotlight is not just a SL problem -- if you install SL it's going to want to index your disk, too...

  • Can I downgrade from pre-installed Lion to Snow Lepoard on Late 2011 MBP i7 2.4?

    I've purchased a MacBook Pro Quad-Core i7 2.4 with pre-installed Lion (no installation DVD's included), but, unfortunately, found out that a big number of audio software doesn't run natively and malfunctions with this version of OS, meanwhile they worked flawlessly on my previous MacBook using Snow Leopard.
    The question is: can I downgrade from pre-installed Lion to Snow Lepoard on Late 2011 MBP i7 2.4?

    Thanks a lot for your reply. I ran into those numerous techy ways of downgrading, but I've found none addressing my particular model (I think I read something about 15", while mine is 17" and sometime it does make difference - because Apple love to keep secrets about what's inside). Since i've got zellions of audio plugins install, I'm trying to make sure that messing around with systems will lead to some fruitful result. So the new question: is there a way to make sure (I haven't found any tech spec threads naming the borderline between a "working variant" and "no-use-trying" variant) - is that just a matter of chance and doing it at one own risk, or is there still a way to make surefire decision?

    Don't downgrade OS X without first erasing the drive. You cannot restore a Time Machine backup of Lion directly on top of a later version of OS X such as Mountain Lion or Mavericks.
    When you "Restore from a Time Machine Backup.", the drive will be erased for you, but yes, won't hurt to:
    Boot into Recovery (hold ⌘R on boot)
    Utility->Disk Utility->Erase Macintosh HD, then Repair Macintosh HD
    Quit Disk Utility
    Then Select: Restore from a Time Machine Backup.

  • How can I make my Lion Server into a Lion Workstation?

    How can I downgrade my Mac OS X Lion Server to just a standard Mac OS X Lion machine?
    I've tried everything including re-installing Lion. When re-installing Lion, it seems to automatically pickup on the fact that this is a Server OS & installs Lion Server OS.
    I want to simply downgrade my Lion machine to be running the standard Lion OS instead of Lion Server.
    In case you're wondering, this is on my iMac 27" which I originally upgraded from Snow Leopard to Lion, then from Lion to Lion Server.

    @Chris BeHanna
    You were right for the firewall Issue. I was also running IPSecuritas and I installed Lion Server and the traffic stopped responding on the tunnel, although it connected well.
    I figured out that, for some reason, even if the ServerAdmin indicated that the server firewall (my local "new" server, my own machine) was inactive, some rules must had been set during Server.app installation.
    Anyway, what I did was activate the firewall, and then, allow all traffic on every ip. You can do that in the ServerAdmin app.
    And then the traffic turned back on, on the IPSecuritas tunnels.
    The next step would be to be configure rules precisely, but since I am already behind a firewall, I prefer using a "transparent" setting.

  • Can I downgrade a new mac mini from 10.8 to 10.6?

    Just purchased a new Mac mini as a filemaker development platform for work. It shipped with 10.8. About half-way through getting it all set up I realized that the Filemaker 11 software I'm using has older plugins, these plugins are only compatible up to OSX 10.6. Can I downgrade this machine to 10.6?  Or can I just upgrade the plugins on this mac mini without impacting all the users of my database who have older platforms and older plugin versions?

    If you have no plans to upgrade Filemake, then I suggest you export your database to a more "universal" format such as Tab Delimited or CSV. These are text formats that almost any other database program can import. Then you can move to a new DB application compatible with Mountain Lion. Mountain Lion contains the SQL database for which there are numerous frontend GUIs.

  • How can I Downgrade to Snow Leopard and keeping all 3rd party apps?

    New to MacBookPro and really happy. With Lion...not so much. I want to downgrade to SL, however, apparently I must reformat the hard drive. Here´s the real question: If I have a backup of my entire HD with the user, docs and all the apps I have installed (on Lion), once I downgrade to Snow Leopard, can I just move all my apps from the back up disk I have made of my Lion-Running hard drive? In other words, How can I downgrade without having to reinstall every single third party app I have?

    First, how new is this Mac?  A Mac as a rule cannot boot to an older operating system version than that with which it was originally supplied.  In other words, if this is a new MBP that came with Lion then you probably cannot get it to boot to SL.
    Some applications (and I take it you do mean full "applications" rather than "apps" which are mobile device programs -- it helps to be clear o terminology) can just be dragged from place to place.  Others, notably Adobe and Office, install things all over the place and unless you are good at finding hidden files with obscure names in 10 different places you will just have to re-install them.

  • How can I upgrade to Lion again from Snow Leopard?

    My Macbook Pro (Late 2011), was shipped with OSX Lion but due to some software compatibility issues, I downgraded my OS to Snow Leopard, but now that software is fully compatible with OSX Lion and Mountain Lion, how can I upgrade to Lion again?

    Hi Viaixtapa, well long story...
    I phoned the number above and purchased a license.  The process worked fine, the Apple Tech took my particulars, I received an email right away acknowelging my purchase and one from the Tech giving me his details so that I could come back to him if I needed help.  But when I went to download Lion it would not download because I do not have the requirements to load it, mine is an Intel Core Duo instead of an Intel 2 Duo or later.
    The clerk in the Apple store in Vancouver checked the details of my machine and told me I could load it if I upgraded the memory.  But apparently that was incorrect.  The Tech I who sold me Lion checked too and said no, my iMac is not capable of supporting Lion.  So a plus and minus answer.  I did get Lion, but was unable to load it, yours is a 2008 model so you should have no trouble.  Why not try the number or the international website above from Steve, nothing ventured, nothing gained.  I will just keep saving my pennies toward a new iMac!!

  • Trying to downgrade Mountain Lion to Lion

    hey team: 
    I've been attempting to downgrade Mountain Lion 10.8.5 to Lion for a client's Mac Pro machine and am having a hard time doing something that I've done easily in the past.
    The Mac Pro came with Lion installed, but for some reason I advised my client to upgrade to Mountain Lion, thinking that Apple would improve their operating system.  Since installing Mountain Lion, he's had trouble with large file transfers crashing, screen turning green / grey and then crashing, FCP 7 frame issues on playback, etc etc
    I've since made a Lion install clone to USB, and my Macbook Pro laptop will boot to that when I hold the Option key.
    Holding the option key on the keyboard on the Mac Pro at startup however, with the same Lion USB inserted, yields the startup tone and a black screen.  No option to boot to an alternate drive.  No Apple logo.  Nothing.
    I've also made a Mountain Lion USB install, and holding option with that inserted, yields the startup tone and a black screen.  No option to boot to an alternate drive.  No Apple logo.  Nothing.
    When I hold Command-Option-R, it will boot from the Mountain Lion USB, but not the Lion USB, even though the same workflow works fine on the laptop. 
    I've even tried booting to my Snow Leopard DVD; the DVD drive spins up for a while, then stops.  All with a black screen.  I understand though that this might be a newer machine that won't support Snow Leopard (which is ridiculous by the way -- how is this good enough Apple?)
    Is there something about 10.8.5 that locks you into 10.8.5 on a MacPro tower?  This machine came with Lion installed, so obviously it can run it.  Why does holding Option on bootup on the MacPro no longer work?  The Option-boot works on my Macbook Pro laptop, which is also running 10.8.5. 
    Thanks for any help and advice!

    Solved my problem cloning an old Snow Leopard machine with Carbon Copy Cloner -- a great free program that saved me this time -- to an external hard drive. 
    Mac Pro still wouldn't Option mount the cloned drive (I'm wondering if it's a hardware problem on this tower), so I set the tower to Target Mode, attached a Firewire to my laptop, and attached the external hard disk with the cloned Snow Leopard machine also to my laptop.
    After the Mac Pro tower drive appeared on my lappy as a firewire drive, I wiped it using my laptop's Disk Utility, then cloned the cloned Snow Leopard external hard drive to the Mac Pro tower hard drive.
    Mac Pro started up fine -- and apparently this tower can run Snow Leopard!  But I then immediately updated to Lion using the USB stick previously mentioned, which was succesful first time out.  Running Software Update brought me up to the latest version of Lion 10.7.5
    Thank goodness for Carbon Copy Cloner -- and that I had a laptop still running Snow Leopard in my arsenal!
